Hi Frank, Personally, I don't re-download it. I just wait for Firefox to be updated but it's really tiresome. When Firefox 36 was released, I couldn't use it more than 10 minutes before it crashed. I'm the kind of guy who has at least 15-20 tabs open at the same time, listening to music (or stuff I'm a buff of) on Youtube, looking up dictionaries, using Photobucket, using Google drive, having tons of softwares working in the background, watching US series on streaming and on, and on, and on (with 8 Go of RAM memory, I can afford it... ). And yet... guess what makes Firefox crash ALWAYS !!!!???? That thing is a "virus" ! That can't be otherwise !
